“Golden tree coral” refers to Laurinque elenya, a bright-yellow, branching octocoral described from Costa Rican Pacific seamounts in 2026. Reported colonies live 360–529 metres below the surface and can exceed one metre in height. A photograph that shows a yellow, tree-shaped colony is not enough for a species-level identification: location, depth, expert morphological examination and, ultimately, molecular evidence are important.
What the name means
Laurinque elenya is the scientific name attached to the coral described in a 2026 paper in ZooKeys. It is the type species of the newly established genus Laurinque and family Laurinqueidae. The common wording “golden tree coral” reflects the colony’s vivid yellow colour and branching, tree-like outline; it is not a formal replacement for the scientific name.

The animal is an octocoral: a colonial cnidarian whose individual polyps have eight-part symmetry. A colony is made of many genetically related polyps living together and contributing to a shared structure. The accessible account of this species does not provide a complete diagnostic description of microscopic structures, skeletal elements or polyp characters. Those limits matter because many unrelated deep-sea corals can look similar in a remotely operated vehicle (ROV) image.
The species name also has a human story. Lead researcher Odalisca Breedy said that seeing the octocoral garden for the first time in 2019 inspired the elvish name used for the taxon. That poetic origin explains why an otherwise technical scientific name appears alongside the descriptive common name, but it does not change the rules for identification: the scientific name must be tied to evidence.

Where it was found
Reported colonies came from seamounts near Isla del Coco and along Costa Rica’s Pacific margin in the eastern tropical Pacific. The documented depth range is 360–529 metres. At those depths, sunlight is weak or absent, and a colony encountered by an ROV is part of a deep benthic community rather than a shallow-water reef.
Some observed colonies were taller than one metre. Height, colour and branching habit are useful field observations, but they are contextual clues rather than a self-contained identification key. A yellow branching octocoral outside the Costa Rican seamount setting, or at a substantially different depth, should not automatically be labelled L. elenya. The known localities are discovery records, not proof that the species occupies every seamount in the Pacific.
Seamount names, coordinates and the depth of the animal itself are especially valuable. “A dive to 500 metres” is not equivalent to “the coral was at 500 metres”; an ROV can move through a broad vertical range during one dive. A reliable record ties the depth to the exact video frame or collection event.
A short discovery timeline
- 2019: Breedy reported seeing the octocoral garden for the first time. The unusual landscape prompted closer study and later inspired the taxon’s elvish name.
- 2023: The team collected additional samples. These material samples made a more extensive laboratory comparison possible.
- 2026: The new species, genus and family were reported in ZooKeys 1283. The accessible announcement was published by Pensoft Publishers through ScienceDaily on October 8, 2026.
This sequence explains why a striking photograph did not immediately produce a species name. An observation can come first, while formal classification follows only after specimens, comparisons and analyses are completed.
Why it is a new family, not just a new colour form
The discovery team initially tried to place the coral using morphology. The preliminary comparison did not match the organism to known genera or families. Three initial genetic markers then produced inconsistent relationships, so the researchers expanded the analysis to phylogenomics, comparing hundreds of genes.
That broader analysis placed Laurinque closest to Eunicellidae in the study’s evolutionary results while supporting recognition of a separate family, Laurinqueidae. “Closest to” describes an evolutionary result; it does not make Laurinque a member of Eunicellidae. The separate family name records the conclusion that the lineage is distinct enough to warrant its own family-level placement.
In other words, the classification is based on genomic evidence in combination with taxonomic examination, not on the fact that the colonies happen to be yellow. A new family is a claim about evolutionary relationships. It cannot be established from a colour photograph or a branching silhouette.

The species description is associated with Odalisca Breedy, Cathy McFadden, Catalina Murillo and Andrea Quattrini. The paper is titled “A coral among stars: A new octocoral family (Anthozoa, Octocorallia, Malacalcyonacea) from seamounts in the tropical eastern Pacific,” ZooKeys 1283 (2026), DOI 10.3897/zookeys.1283.191899.
What the discoverer said
Breedy described the sequence from first sighting to formal placement this way:
“I saw the octocoral garden for the first time in 2019 and I was impressed by the beauty of the landscape, which inspired, later the elvish name of the taxa. I thought the species could belong to a known family and genera, but after the preliminar morphological analysis I realised that it was something very different that I could not match with the known taxa.
“In 2023 we collected more samples and thanks to the exhaustive molecular analyses made by my colleagues, Cathy McFadden, Catalina Murillo and Andrea Quattrini, we were able to determine the taxonomic placement of the stunning species, in one of the most enigmatic sites.”

How to identify a reported specimen responsibly
Use the following process when evaluating an ROV frame, expedition photograph or observation record. It separates a defensible report from a guess based only on colour.
1. Preserve the original observation data
Save the unedited image or video frame and record the expedition, dive, date, camera system and any specimen or sample number. Keep the original file because cropping and colour correction can remove scale or alter the apparent hue. If a public image has been downloaded, retain its original link and caption as well as your working copy.
2. Confirm the geographic setting
Check the coordinates, seamount name and regional description. A record that fits the eastern tropical Pacific seamounts near Costa Rica is more consistent with the published occurrence than an image from another ocean basin. If the location is unknown, describe the organism generically rather than assigning the species.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitches3. Check depth, not just the dive’s maximum depth
Use the depth at which the colony itself was filmed or collected. The reported range for L. elenya is 360–529 metres. A dive that reached 500 metres does not prove that every organism in the video was at 500 metres; the frame’s own depth or the specimen’s collection record is needed. Record metres and, if supplied, the instrument or navigation source used to calculate depth.
4. Describe visible form without over-interpreting it
Note the vivid yellow appearance, branching architecture, tree-like colony shape and approximate size. Include whether the colony is solitary or part of a garden, how it is attached to the substrate and whether a scale reference is visible. These observations support comparison but do not replace examination of taxonomic characters. Separate direct observations (“yellow branches visible”) from interpretations (“therefore this is L. elenya”).
5. Compare with an expert identification resource
NOAA’s Benthic Deepwater Animal Identification Guide combines images with taxonomic names, depth, location and expert review. NOAA’s 2024 announcement for its fourth-version guide described 6,322 images and observation fields that can include taxonomy, coordinates, depth, ocean, region, locality and a dive link. Search the guide by the recorded region and depth rather than by colour alone. A guide match is a useful comparison, not automatic proof that a new image belongs to the same species.
6. State the identification level clearly
If the record has only a photograph, use wording such as “yellow branching octocoral, tentatively resembling Laurinque elenya.” If geography and depth fit but no specimen or expert review is available, retain “tentative.” Reserve a species-level assertion for a determination supported by the published description, expert-reviewed imagery or specimen-based analysis.
7. Use molecular confirmation when required
The discovery itself demonstrates why genetics can be necessary: three genes did not give a consistent placement, while a data set containing hundreds of genes resolved a distinct lineage. A formal confirmation may therefore require tissue, appropriate permits and laboratory sequencing rather than a visual match. Do not infer that a hobbyist DNA result is comparable to the phylogenomic analysis without expert interpretation.
8. Preserve uncertainty in the final caption
Do not remove qualifiers when an image is reposted. “cf.”, “aff.” or “tentatively resembling” communicates that the comparison is provisional. If later expert review changes the determination, update the caption and retain the earlier version in the record so the identification history remains traceable.
What a photograph can—and cannot—show
| Observation | What it supports | What it cannot establish alone |
|---|---|---|
| Bright yellow colour | Consistency with the reported appearance | Species identity; lighting, camera settings and other yellow octocorals can produce a similar look |
| Tree-like branching colony | Consistency with the common-name description | Relationship to Laurinque or any particular family |
| Colony over one metre tall | Compatibility with the size reported for some colonies | That every large colony belongs to this species |
| Depth of 360–529 m | Matches the published occurrence range | Identification without geographic and taxonomic evidence |
| Costa Rican Pacific seamount location | Matches the known regional setting | Confirmation when the image lacks diagnostic characters or expert review |
| Visible scale marker or ROV laser | More reliable estimate of colony height | Species identity; scale solves size, not taxonomy |
| Unedited frame with metadata | Allows others to check lighting, depth and context | Replacement for a specimen-based determination |
Do not confuse it with “gold corals”
NOAA’s older coral reference uses “gold corals” for Gerardia species, a separate deep-sea group. That material describes rigid, branching, tree-like colonies, including examples around Hawaii and the Straits of Florida. The shared words “gold” or “golden,” and a broadly similar branching form, do not show that Gerardia and Laurinque are the same lineage.
| Feature | Laurinque elenya (“golden tree coral”) | Gerardia (“gold corals” in NOAA material) |
|---|---|---|
| Taxonomic status | Species in the new genus Laurinque, family Laurinqueidae | Separate group identified by the genus Gerardia |
| Documented setting | Costa Rican Pacific seamounts near Isla del Coco and the Pacific margin | Examples discussed from Hawaii and the Straits of Florida |
| Depth information in the cited material | 360–529 m | Not stated here as a single comparable range |
| Safe label for an unidentified image | Yellow branching octocoral, possibly Laurinque | Do not use “gold coral” solely because the colony is yellow or tree-shaped |
When writing a caption or database entry, include the scientific name only when the evidence supports it. If the source uses “gold coral” for Gerardia, retain that name for that group rather than treating it as a synonym for the Costa Rican species. Common names are useful for public communication, but scientific names prevent this particular mix-up.

NOAA describes deep-sea corals as colonies of small animals that build a shared skeleton. They inhabit dim or dark water and obtain food from microscopic organisms carried by currents rather than relying on sunlight-driven photosynthesis. Tree, feather, column and fan forms can provide three-dimensional habitat for other animals.
These general features explain why a branching colony can form a visible “garden” on a seamount. Branches extend the feeding surface into moving water, while the shared structure creates space that other animals may use. Those statements describe deep-sea corals generally; they are not species-specific measurements for L. elenya. The accessible account of the discovery establishes the coral’s colour, branching habit, size observations, location, depth and classification, but it does not quantify this species’ growth rate, diet, lifespan, reproductive cycle or associated fauna.
NOAA Ocean Exploration reports more than 3,000 identified deep-sea coral species. NOAA also states that over half of all known coral species occur in deep, dark waters. Neither figure is a count of species in the genus Laurinque; they provide scale for the broader, still-diverse deep-sea coral environment. The figures also explain why an unusual-looking colony should be documented carefully rather than assigned a name from a quick visual resemblance.
Why identification is difficult
Convergent colony shapes
Branching is an effective way for a suspension-feeding colony to occupy flowing water, so unrelated corals can independently develop tree, fan or feather outlines. Shape therefore narrows the possibilities without determining ancestry. A branching silhouette is a starting observation, not a family diagnosis.
Recommended Free Tools
Colour changes with imaging conditions
ROV lights, camera white balance, distance, suspended sediment and post-processing can change how yellow appears. A colour description should be accompanied by the raw image and lighting details whenever possible. A faded or overexposed frame may not preserve the apparent yellow at all.
Scale is easy to misread
Without a laser scale, manipulator arm or known object in the frame, a colony may look larger or smaller than it is. A statement that some colonies exceed one metre comes from documented observations, not from visual estimates of every photograph. Record whether the one-metre comparison was measured directly or inferred from an expedition scale reference.
Taxonomy may require characters below image resolution
Features used by specialists can involve skeletal structure, polyp arrangement or microscopic anatomy that an ROV overview cannot resolve. The Costa Rican coral’s own history—an initial morphological mismatch followed by expanded genomic analysis—illustrates this limitation. Even a close-looking image cannot reveal every character used to delimit a species or family.
Common names compress different taxa
“Golden tree coral” describes an appearance, while “gold coral” has also been used for Gerardia. Searching or tagging by common name alone can therefore combine unrelated records. Pair every public name with a scientific name and locality when the determination is known.

What is established—and what remains open
Established information includes the scientific name, the new genus and family, the bright-yellow tree-like colonies, the Costa Rican seamount setting, the 360–529 m depth range, observations of colonies taller than one metre and the phylogenomic basis for classification. The 2026 ZooKeys treatment is the taxonomic reference for those claims.
The accessible reporting does not supply every anatomical character needed to build a stand-alone field key, nor does it establish population size, global distribution, conservation status, age structure or ecological interactions for the species. It also does not provide a measured growth rate or a complete account of reproduction and feeding. A reader should not turn the known discovery localities into a claim that the coral occurs throughout the Pacific, nor infer rarity or abundance from the existence of a few reported colonies.
How to use the name in everyday writing
On first mention, write “the golden tree coral, Laurinque elenya.” Use the italicized scientific name thereafter. If the evidence is only a photograph, write “a yellow branching octocoral tentatively resembling L. elenya.” Avoid calling an unidentified specimen “gold coral,” because that wording is also used for Gerardia and can create a taxonomic error.
For a news caption, the most informative compact description is: “Bright-yellow branching octocoral Laurinque elenya, reported from Costa Rican Pacific seamounts at 360–529 m.” Add “tentative” if the image lacks a confirmed determination. For a database, include the depth and locality in separate fields so a later user can filter observations without treating a common name as a formal identification.
Frequently asked questions
Is the golden tree coral a true coral reef builder?
Laurinque elenya is an octocoral, a colonial cnidarian. NOAA’s general description says deep-sea corals are colonies of small animals that build a shared skeleton, but the available species account does not quantify this species’ skeleton, growth rate or reef-building contribution. It is safest to call it a deep-sea octocoral rather than assign it a reef role that has not been documented for this species.
Where exactly was it discovered?
Reports place it on seamounts near Isla del Coco and along Costa Rica’s Pacific margin in the eastern tropical Pacific. The accessible account does not provide a complete list of coordinates for every colony. Use the expedition record or taxonomic paper for any precise locality, and do not expand “Costa Rican seamounts” into a claim of distribution across the whole Pacific.

A free scan shows the junk files, broken settings and background clutter dragging Windows down - then fixes them in one click.Free scan · Windows 10 & 11How deep does it live?
The reported colonies occur from 360 to 529 metres. That range describes documented observations, not a guaranteed biological limit. A new record outside the range would need independent verification rather than being rejected or accepted solely from a photograph.
Can I identify it from a yellow, tree-shaped picture?
No. Yellow colour and branching form are consistent with the common description, but they are not diagnostic by themselves. Add the image’s location, the depth of the colony, a scale reference and expert comparison. If those data are missing, label it a yellow branching octocoral and keep the species assignment tentative.
Is it the same as NOAA’s “gold corals”?
No. NOAA uses “gold corals” for Gerardia species, a separate group discussed from places including Hawaii and the Straits of Florida. Similar common-name wording and tree-like branches do not establish a relationship. Use Laurinque elenya for the Costa Rican species and Gerardia for the other group when that identification is supported.
Why did scientists need hundreds of genes?
Three initial genetic markers produced inconsistent relationships. A broader phylogenomic comparison of hundreds of genes provided a clearer evolutionary placement, near Eunicellidae but distinct enough for the new family Laurinqueidae. The example shows why a few markers or visual resemblance may not resolve an unusual lineage.

What do scientists know about its diet and lifespan?
The accessible species account does not report a measured diet, lifespan, growth rate or reproductive cycle. NOAA explains that deep-sea corals generally obtain microscopic food carried by currents, but that broad description should not be presented as a species-specific study of L. elenya.
What is the most cautious label for an unverified image?
Use “yellow branching octocoral, tentatively resembling Laurinque elenya,” and include the image, depth and locality if known. A species-level label is appropriate only when the published description and expert or specimen-based evidence support it.
The answer in one sentence
A golden tree coral is the recently described Costa Rican deep-sea octocoral Laurinque elenya; identify it by combining its yellow branching form with the documented region and depth, then seek expert and molecular confirmation rather than relying on appearance alone.

Frequently Asked Questions
What is a golden tree coral?
It is the common-name description associated with Laurinque elenya, a bright-yellow, branching octocoral from Costa Rican Pacific seamounts. The scientific name is more precise than the common name.
Where and how deep does Laurinque elenya live?
Documented colonies were reported from seamounts near Isla del Coco and Costa Rica’s Pacific margin at 360–529 metres depth.
Can a photograph confirm the species?
No. Colour and tree-like branching are clues only. A defensible identification also needs location, the colony’s actual depth, taxonomic comparison and, when necessary, specimen-based molecular analysis.
Is golden tree coral the same as gold coral?
No. NOAA uses “gold corals” for Gerardia species, a separate group. Similar names and branching forms do not make Gerardia and Laurinque synonyms.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesWhy was a new family created?
Three initial genes gave inconsistent relationships. A phylogenomic analysis of hundreds of genes placed Laurinque near Eunicellidae while supporting a distinct family, Laurinqueidae.
How large are the colonies?
Some reported colonies exceed one metre in height. Size alone cannot identify the species and should be estimated with a visible scale reference.
What should I write if my image is unverified?
Use “yellow branching octocoral, tentatively resembling Laurinque elenya,” and record the image source, location and depth rather than asserting a confirmed species.
The Bottom Line
Bottom line: The golden tree coral is Laurinque elenya, a 2026 Costa Rican octocoral placed in the new family Laurinqueidae. Its yellow, tree-like form is distinctive at a glance, but reliable identification combines that appearance with seamount location, 360–529 m depth, expert taxonomy and—when needed—molecular evidence. Do not confuse it with NOAA’s separate Gerardia “gold corals.”
